Preparing your environment for the Duolingo English Test is one of the easiest ways to avoid invalidations and improve your overall performance. At DET Study, weโve seen how a proper setup leads to smoother testing and faster certification. Hereโs a simple, practical guide to help you get ready.
1. Choose a Quiet, Private, Well-Lit Room ๐๏ธโจ
A great test starts with a great environment. Choosing the right room helps proctors clearly see you and ensures your test runs smoothly.
A quiet, private room with good lighting helps create the stable testing environment that DET requires.
The Beginnerโs Guide to the Duolingo English Test (DET)
Tips from DET Study:
- Close the door and avoid interruptions
- Use a simple background (plain wall is best)
- Avoid shadows or light behind you
2. Check All Devices and Your Secondary Camera ๐ฑ๐ป
Your equipment is the foundation of your test. A quick setup check ensures everything works correctly before you begin.
The DET relies on both your computer and your phone, so testing your devices ahead of time prevents delays or invalidations.
Make sure you have:
- A laptop/desktop
- Stable Wi-Fi
- Webcam + mic
- Smartphone (secondary camera)
- DET desktop app
Room Scan & Ear Scan:
Youโll use your phone to show the full room and confirm no earbuds are being worn.

Secondary Camera Tips:
- Connect to Wi-Fi
- Keep the phone charged
- Place it on a stable surface
- Ensure it shows your screen, keyboard, and hands
Run the DET system check 1โ2 days before testing.
3. Create a Clean, Simple Workspace ๐งน๐ช
A clutter-free desk reduces distractions and speeds up your room scan. Proctors should clearly see only the items required for the test.
A clean workspace also prevents accidental rule violations.
Your desk should include only:
- Your computer
- Your phone (secondary camera)
- Your ID
Remove books, papers, headphones, and any extra electronics.
4. Optimize Your Lighting & Camera Angles ๐ก๐ฅ
Good lighting helps both cameras capture your face clearly throughout the test.
A well-lit setup reduces the chance of proctor reviews or certification delays.
Tips:
- Use natural light when possible
- Keep lamps in front of you
- Keep your laptop camera at eye level
- Ensure your phone camera has a clear view of your keyboard and hands

Before you begin:
- Take a few deep breaths
